One view is that by the choice of JPEG as a file format, the user has already stated that their goal for this image is moderate file size over lossless storage. An application could therefore be considered to be behaving reasonably in processing such a file, if it introduced no noticeable additional degradation in quality. Since by the choice of the JPEG format image information has already been thrown away, a small additional loss of information is unlikely to be noticeable (ie. retaining similar or better quantization tables) and is consistent with the users implicit goals. Defaulting to a lossless format when the original file is a JPEG could be seen as poor application behaviour, since it is contradicting the users implicit preferences.
